A mini stroke, or transient ischemic attack (TIA) is a brief episode characterized by neurological symptoms. A mini stroke is a serious event because it is often the warning sign of an impending stroke. The symptoms of a mini stroke begin suddenly and vary depending on the part of the brain that is affected.
The following offers an estimated range of how long alcohol stays in your blood, urine and saliva: 1  Saliva test: One to five days. 2  Blood test: 12 hours. 3  Urine test: Three to five days via Ethyl Gluconoride (EGT) metabolite.  Breathalyzer test: Up to 24 hours.
Alcohol itself stays in your system for 1-1.5 hours for each drink you take, plus approximately 1 hour delay for the initial drink -- this is when it's detectable in breath and blood, and when it will affect you. It then stays in your urine for another hour or so, where it's detectable in a urine test.
